Check or create a recovery partition by diskpart

# X/y is the target disk/partition
DISKPART> select disk x
DISKPART> list partition
DISKPART> select partition y

#The recovery partition looks like:
DISKPART> detail partition

Type    : de94bba4-06d1-4d40-a16a-bfd50179d6ac
Hidden  : Yes
Required: Yes
Attrib  : 0X8000000000000001

# If no recovery partition, create one and set below properties. Only "set id=27" is needed for BIOS
DISKPART> set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
DISKPART> gpt attributes=0x8000000000000001

# Keep the recovery partition/volume active from above steps.
DISKPART> format quick fs=ntfs label=”Windows RE”
DISKPART> assign letter=R

Prepare the Windows RE image “Winre.wim” from below location

"C:\Windows\System32\Recovery\Winre.wim"
#If the file doesn't exist, usually because WinRE has been moved to the RE tools partition prior to capturing the image. Get it from the mounted windows installation install.wim

> dism /mount-image /ImageFile:"D:\sources\install.wim" /index:4 /mountdir:"C:\WinInstall_mount" /ReadOnly
"C:\WinInstall_mount\Windows\System32\Recovery\Winre.wim"

# Now copy winre.wim to the recovery partition:
mkdir R:\Recovery\WindowsRE
xcopy /h C:\Windows\System32\Recovery\Winre.wim R:\Recovery\WindowsRE

# Unmount install.wim after done copying
dism /unmount-Image /MountDir:"C:\WinInstall_mount" /discard

Register the winre.wim image

reagentc /setreimage /path R:\Recovery\WindowsRE /target C:\Windows
reagentc /enable
reagentc /info
